I have left for the port as early as 10am for Miami and once completed check in had a short 10-15 minute wait for my number to be called to board. Boarding can start as earlt as 11:30am.
Fort Lauderdale I was at the port by 10:30 and checked in and waiting by 10:40. We had to wait until 11:30 for the last guests to clear customs so we could get on. They opened boarding at 11:30 and I had tag #3 so once I got through the pictures and such I was on the ship at 11:38am!!!!
